Currently there are trace events for the various RAS
errors with the exception of ARM processor type errors.
Add a new trace event for such errors so that the user
will know when they occur. These trace events are
consistent with the ARM processor error section type
defined in UEFI 2.6 spec section N.2.4.4.

According to the kbuild failure, I'm guessing this file requires a:
#include <ras/ras_event.h>
I add that include in patch 8/10 of this series, so ghes.c has the
include before this patch. The kbuild
complained about the same thing for both trace events added in this
series. Upon further debug, it
looks like I'll need to verify that CONFIG_RAS is enabled to make these
trace event calls. It's strange
that kbuild didn't complain in earlier versions of this series because
these have been this way the
whole time :) I'll add the config check in the next series.
Thanks,
Tyler
